Grain Handling & Processing

Handling and processing grain brings many challenges, such as high volumes, high speed applications - making efficiency a top priority all while dealing with combustible dust!

4B has a long history in serving the grain industry. The company introduced the first grain elevator bucket back in 1909 and has since been leading the field in supplying top quality components for grain elevators and conveyors. 4B has designed and optimised many grain elevators over the years, and many of the technologies used in modern grain elevators, such as high efficiency buckets operating on centrifugal discharge systems.

4B has pioneered the development of electronic monitoring components back in 1984, introducing the first complete elevator / conveyor monitoring system, the Watchdog Elite. 4B’s electronic components have been integral part of conveying systems throughout the grain industry ever since and have become a reference in many grain handling facilities, port facilities, and grain storage systems across the globe.

Grain handling is inherently dangerous, especially in a bucket elevator, where all the factors for an explosion are present: highly combustible grain dust, a confined area, oxygen, and a potential ignition source in the form of overheated bearing, belt slip or misaligned belts or pulleys.

4B engineers can recommend the right sensors and monitoring systems to protect your grain facility, no matter if it is just a single elevator or a complete installation consisting of many elevators and conveyors.

Elevator Re-Design from Grain to "Green Malt"

A malting facility repurposed a grain elevator to transport "green malt" and found that the elevator was not functioning properly. 4B reduced the elevator pulley size and RPM to give the correct discharge, and modified the outlet. Elevator running smoother with less loading on the motor.

Securing Overlap Belt Splices on Elevator

A North American grain storage facility was concerned that the bolts used to secure the overlap splice section of an elevator leg belt were prone to pull through. 4B offered a solution using Ref70 large diameter elevator bolts in combination with unique oversized oval washers.
